Dear colleagues, I herewith report the detection of an outburst of TK5 Lyr. I found the object on a 2001, June 18.973 UT CCD image, acquired using the 0.35-m f/6.3 telescope at CBA Belgium Observatory. The detection was made as part of a new, fully automated dwarf novae CCD search programme (more information on this will appear later on my web site), that I recently developed. Some details : 2001, June 18.973 UT, mag 15.2 unfiltered. CCD images of the outbursting object, as well as additional information and the intermediate status of our ongoing CCD photometry run on TK5 Lyr, are available on my web site.
